MOODYS CORP

Moody's Corp. (MCO, CUSIP 615369105) entered Q1 2026 with $66.1B of institutional 13F value across 1,329 institutional accounts — a holder breadth appropriate for the world's largest credit-rating agency and financial-information-and-risk-management franchise, whose primary businesses span (1) credit ratings (Moody's Investors Service — corporate, government, structured-finance ratings), (2) risk-management software and analytics (Moody's Analytics — credit scoring, financial modeling, regulatory capital, data subscriptions for banks and insurers), and (3) emerging-data and alternative-data products. The defining Q1 signal: Berkshire Hathaway reduced its MCO position by $1.84B, making this the single-largest named seller of the quarter across this batch, while Egerton Capital (UK) added $279M — a rotation consistent with a long-term concentrated holder (Berkshire) trimming a large multi-year position alongside a fundamental hedge-fund or long/short manager building at the financial-infrastructure sleeve tier. For smart-money trackers, MCO's Q1 filing carries signal weight disproportionate to its normal coverage because Berkshire's $1.84B reduction is an unusual large-quarterly-exit event from a famously long-term-oriented holder, suggesting either portfolio-rebalancing at the insurance-float or concentrated-public-equity sleeve level, or a fundamental readjustment on credit-market and rating-agency dynamics.
